Shanghai Yichuan RF admittance level gauge (Yichuan)

Shanghai Yichuan RF admittance level gaugeCommonly known as radio frequency admittance switch or radio frequency admittance level meter, radio frequency admittance level meter is widely used in several typical applications, including chemical drugs, plastics, films, feed/grains, rubber, pharmaceuticals, liquids, wastewater, sand, food, mud, cement, powders, coatings/fabrics, coal, granular solids, oil, pulp, etc.

working principle
The structure of the RF admittance level gauge product is divided into two parts: the main electrode and the compensating electrode. By applying a set of RF signals between the main electrode and the compensation electrode, it has excellent anti sticking and hanging characteristics, and is a new type of material/liquid level measurement product that replaces capacitive level switches.
Due to the presence of the protective electrode, the detection circuit compares the signals of the detection electrode and the protective electrode to overcome the influence of material adhesion on level measurement.
